when you are participating in ICO, you should be able to take advantage when you enter the place of exchange, whereas if the process of registering to a place of exchange is very long, then surely you will only get a loss because it will make investors disappointed and many will sell at low prices.
I stopped joining ico and chose another model for several reasons like you mentioned, the raw reason from the developer is that market conditions are still downtrend.
When ico goes on they should also have matured with an exchange of no more than 2 months, in fact not.
Investors like me can be patient for so long, but others don't care and they end up selling on the black market. Dev was supposed to strengthen their project, but instead panicked to sell and the project was bleak instantly. Ico dev must also think about this continuity.
